A rain gauge observation station using a water level meter and a remote data transmission unit continuously measures and records precipitation! What is the sponge city concept aimed at solving concentrated heavy rainfall and the urban heat island phenomenon?

At the "Innovation Lab" near Keller's headquarters, you can experience the "Sponge City." Keller's rain gauge observation stations equipped with sensors continuously measure and record precipitation.
What is a Sponge City?
The purpose of a Sponge City is to temporarily store and infiltrate rainwater on-site, processing it in a way that is closer to nature rather than directly draining it away. Soil and plants absorb water like a sponge and later release it through evaporation. This concept models a natural surface that can absorb far more water than paved urban areas. Rain gauge observation points, like those set up in the Innovation Lab, provide crucial data for long-term evaluation of the effects of such urban design.
Keller's sensors in action
At the Innovation Lab, the water level in areas where rainwater is stored is measured with high precision using the 36XW level gauge. The 36XW can measure not only water level but also water temperature simultaneously. The collected data is transmitted to the cloud via the remote data transmission unit ARC1 and displayed live. Additionally, the ARC1 measures atmospheric pressure and ambient temperature under direct sunlight, allowing for an understanding of the impact of sunlight on plants.
